This 0.8 mile trail allows you to access the Betasso Preserve trail system from Fourmile Canyon. To use this trail, you should ride from town - there is no parking and no trailhead at Fourmile Canyon Road.
This trail also enables more adventurous (stubborn? jonesing for miles?) mountain bikers to make a loop from Boulder without repeating trail - check out the Super Betasso route description for more info.
The Betasso Link Trail is a short steep climb that's most often used when riding to or from Betasso from Boulder. To get to it, either ride up the Boulder Creek Path to where it dead ends at Fourmile Canyon and then jump onto Boulder Canyon Drive (Highway 119), or park at the head of the trail just before the tunnel on Boulder Canyon Drive.
The Benjamin Loop singletrack opened on May 17, 2011, and in the process doubled the amount of trail at Betasso. It's a loop, connected by a short stem to the current Canyon Loop, and also to Foumile Road via the Fourmile Link Trail.
This is a swoopy, flowy, gorgeous trail, much like the Canyon Loop. The trail twists and turns, with moderate climbs no matter which direction you're traveling. It's a hoot, and is especially fun when combined with the other trails in this park.
The Canyon Loop is a short but stunningly beautiful 20 minute lap.From either parking lot or the Betasso Link Trail, take the Canyon Loop Trail in the required direction. Both directions are fun and the county usually changes the required direction on the 1st of every month. You start at a high point and descend about half way before climbing back up to where you started. The trail is bench cut on a steep slope. So although the trail is technically pretty easy, it can cause problems for those with a tendency for vertigo.
